Marching Cubes
 - Exploits a coarser Mesh then MT but produces less triangles
 - no use in commercial projects. Algorithm is patented by General Electric Company
 - based on "Marching Cubes: A High Resolution 3D Surface Construction Algorithm"
   by W.E.Lorensen and H.E.Cline

Marching Tetrahedron
 - Finer Mesh
 - better feature preservation
 - patent free
 - based on "A new tetrahedral tesselation scheme for isosurface generation"
   by S.L.Chan and E.O.Purisima

Lookuptables
 - by Paul Bourke (http://astronomy.swin.edu.au/~pbourke)

Overall
 - Simple Data Structures to store Mesh. Vertices are calculated and stored twice
   or even more often.

Processing steps
----------------
1. Enter size of data
2. Load data
3. Enter isovalue
4. Extract Iso Surface
5. Display
